I’ve only tried using that combo a couple of times, but I followed directions exactly. I used Come Clean, then Knot Today and finally topped off with the Curling Custard. When I felt the weird drag, I added more water until the feeling was gone. I can’t say I had white flakes but it took just as long as UFD to dry. So yeah, I sympathize with you about the dry time.
There are so many people online who have combos to pair with the leave-in or the custard. So your options are endless. Though, many of those same people say to not be heavy handed with the original combo, but I could have put way more on the crown and front area to avoid frizz.
I just know in the tips section of the official kinky curly website they say the following:
WHEN MY HAIR IS DRY I END UP WITH A WHITE FILM / WHITE CHUNKS IN MY HAIR?
Another product you are currently using or have used in the past is not mixing well with the Curling Custard. You must shampoo your hair to remove the buildup.
I USED YOUR COME CLEAN SHAMPOO AND I STILL HAVE WHITE STUFF IN MY HAIR?
Come Clean shampoo will remove mild to moderate buildup. If you have used a heavy duty silicone product or a product with an ingredient like beeswax or lanolin we suggest you mix a pinch of baking soda with the Come Clean shampoo in the palm of your hand and use this to wash your hair. This will clean your hair without using a harsh clarifying shampoo.
MY HAIR FEELS STICKY?
Your hair was not wet enough to allow the product to be diluted and distributed evenly enough. Try again and make sure hair is completely wet when applying the Curling Custard. Keep a spray bottle with water close by to re-wet sections if they start to dry.
I’m not saying you used any product or had residue impeding your results. I know for a fact there are several products that in theory should work but just flake on me. But have you ruled out everything that could cause the white flaking before you give up on the combo? Unfortunately, I don’t think there is any help for the 10 hr dry time.
